[0002] At present, single-layer iron storage tanks are widely used in chemical, printing and dyeing, ink, gas stations and other underground storage tanks. When single-layer iron storage tanks store chemical solvents, petroleum and other flammable, explosive or toxic substances, due to Hazardous chemicals and toxic substances have factors such as physical corrosion and electrolytic corrosion. Ordinary single-layer iron storage tanks are buried in the ground all year round, and are corroded by groundwater and electrolytic corrosion. The quality and service life of single-layer iron storage tanks have obvious differences. Potential safety hazards, related to safety, economy, and environmental protection

Embodiment Construction
[0017] The present invention will be further described now in conjunction with accompanying drawing.
[0018] like figure 1 As shown, a buried double-layer storage tank includes a steel inner shell 2, a winding silk tape, a PET isolation film, and an FRP outer shell 1 in sequence from the inside to the outside. Among them, the winding filamentary tape is wound 360° around the outer surface of the tank of the steel inner shell 2, and the PET isolation film is wrapped on the outer surface of the winding filamentary tape, and the winding filamentary tape and the PET isolation film form a tiny interlayer 3, PET isolation The outer surface of the membrane has an FRP shell 1, and the top of the buried double-layer storage tank is provided with a leak detection pipe interface. The detection sensor 7 of the remote monitoring leak detection system 6 is installed at the bottom of the leak detection pipe 5 and communicates with the tiny interlayer 3. The bottom of the leak detection tub...

The invention relates to a buried double-layer storage tank, which sequentially comprises an inner steel shell, a tiny sandwich and an FRP (Fiber Reinforced Plastic) outer shell from the inner shell to the outer shell, wherein the tiny sandwich, which is a hollow layer, comprises a coiled threadlike adhesive tape and a PET (Polyethylene terephthalate) isolating membrane; the coiled threadlike adhesive tape is coiled on the outer surface of the inner steel shell; the PET isolating membrane is coated on the outer part of the coiled threadlike adhesive tape; the FRP outer shell is coated on the outer surface of the PET isolating membrane; the buried double-layer storage tank also comprises a remote monitoring leakage detection system; the remote monitoring leakage detection system is inserted into the bottom of a leakage detection pipe from the top of the storage tank leakage detection pipe and communicated with the hollow layer of the tiny sandwich; and a detection sensor of the remote monitoring leakage detection system is installed on the bottom of the leakage detection pipe and communicated with the tiny sandwich. The buried type double-layer storage tank has the advantages of strong acid and alkali resistance and electrolyte resistance, the FRP outer shell layer has small possibility of leakage, and the buried double-layer storage tank is superior to the common buried storage tank in the aspects of safety, economy, environmental protection and the like.
Description
technical field [0001] The invention relates to a container for storing articles or materials, in particular to a buried double-layer storage tank for storing chemical solvents and petroleum products. Background technique [0002] At present, single-layer iron storage tanks are widely used in chemical, printing and dyeing, ink, gas stations and other underground storage tanks. When single-layer iron storage tanks store chemical solvents, petroleum and other flammable, explosive or toxic substances, due to Hazardous chemicals and toxic substances have factors such as physical corrosion and electrolytic corrosion. Ordinary single-layer iron storage tanks are buried in the ground all year round, and are corroded by groundwater and electrolytic corrosion. The quality and service life of single-layer iron storage tanks have obvious differences. Potential safety hazards involve safety, economy, and environmental protection. Contents of the invention [0003] The technical probl...
